ok thanks for the help on the catalytic converter. i went to a shop to have them look at it and they said indeed it is bad. They want to charge me 500! for a universal fit one. I found at my local auto parts store that they can order me a direct fit one for around $80. so i think that is the way i'm going to go and do it myself. now how about my front end problem?

On the vibration, it would be worth having the tires balanced, the pulling does point toward a caliper or brake line hose not releasing. Mileage doesn't matter, heating and warping can occur on any rotor. If a caliper or line isn't releasing, that would heat up a rotor and could lead to warping.

As far as balancing goes, it only takes one tire out of balance to shake the stuffing outta ya. If the tires haven't been balanced, I'd try that first, since it'* cheap enough and should be done with an alignment anyway, IMO.

ok i'll try that but my question on the balancing is ....should i just wait until i get new tires (3 weeks or so) or should i go do it now...basically what i'm asking, if i don't balance them soon will it hurt my car or is it ok to go 3 weeks or so?

As long as you aren't in danger of shaking anything loose, lol, you could go the three weeks and wait for the new tires, IMO.

In the meantime, if you find yourself chomping at the bit, it'* easy enough to pull each tire off and check the runnout on each rotor. Plus, you can easily check the condition of the brake lines at the same time to make sure one isn't collapsed.
